Its a black dial Seamaster Calendar 2489 7 SC caliber 503 in rose capped gold. The guy says that was the same model used by Elvis. The condition is mint, also have the original box, 2k asking, my question is does it worth all that money? He says that was bought from Douglas Gravina, an Omega collector here in Brasil.
Who cares if it's the same model as Elvis, it not Elvis's watch. Even if it were "mint" which it isn't even close to it's overpriced by more than $1000. Without a proper head on dial shot one couldn't speak to it's originality.
Does it come with the box pictured..? EDIT: I read now that it does - I am not 100% sure that's for a Seamaster Calendar, however it does fit a Seamaster 300 and is, IIRC, pretty expensive on its own.
